Condolences, offers of help and miracle story on social media after one more tragedy hits France

At least 84 died and scores were wounded after a gunman slammed his truck into a crowd

People across the world turned to social media to express their shock, extend condolences and, in some cases, offer help after the attack in the southern French city of Nicehas left at least 84 people dead and scores injured.

Reminiscent of #JeSuisCharlie and #JeSuisParis, a new hashtag #JeSuisNice has emerged on social media in response to one more tragedy in France.

#PorteOuverteNice, or Open Door, has been used by many Twitter users in Nice offering their homes to those needing somewhere to shelter.

Users encouraged each other not to share their addresses online, but to privately send them through direct messages. Local taxi drivers were also offering free rides to those in the area.
